Q
What does MCV tell us?
A
Mean Corpuscule Volume
SIZE
Microcytic = small cell <80
Normocytic = normal cell 80-96
Macrocytic = abnormally large cell > 96
2
Q
What does MCHC tell us?
A
mean cell hemoglobin concentration
- the COLOR/hemoglobin concentration
“-chromic”
normal color = normochromic 31-37
pale = hypochromic MCHC < 31
3
Q
small RBCs are ALWAYS
A
pale/hypochromic RBC
4
Q
What does RDW tell us?
A
RBC distribution width
new cells differ in size compared to old cells (smaller or larger)
how varied new cells are to old cells
5

6
Q
In an evolving macrocytic anemia, as MCV ____, RDW _____
